Merge tag 'pinctrl-for-v3.8' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl

Pull pinctrl changes from Linus Walleij:
 "These are the first and major pinctrl changes for the v3.8 merge
  cycle.  Some of this is used as merge base for other trees so I better
  be early on the trigger.

  As can be seen from the diffstat the major changes are:

  - A big conversion of the AT91 pinctrl driver and the associated ACKed
    platform changes under arch/arm/max-at91 and its device trees.  This
    has been coordinated with the AT91 maintainers to go in through the
    pinctrl tree.

  - A larger chunk of changes to the SPEAr drivers and the addition of
    the "plgpio" driver for the SPEAr as well.

  - The removal of the remnants of the Nomadik driver from the arch/arm
    tree and fusion of that into the Nomadik driver and platform data
    header files.

  - Some local movement in the Marvell MVEBU drivers, these now have
    their own subdirectory.

  - The addition of a chunk of code to gpiolib under drivers/gpio to
    register gpio-to-pin range mappings from the GPIO side of things.
    This has been requested by Grant Likely and is now implemented, it
    is particularly useful for device tree work.

  Then we have incremental updates all over the place, many of these are
  cleanups and fixes from Axel Lin who has done a great job of removing
  minor mistakes and compilation annoyances."
